Seminar stochastic geometry and its applications
Prof. Dr. Evgeny Spodarev
Dr. Vitalii Makogin
Date and Place
It will be a two-day block-seminar. The first day is January 13 (Friday) 9:00-17:00. The second day is January 20 (Friday) 8:00-15:00. Place: O28/2004 (13.01.2017), HeHo22/E03 (20.01.2017)
The level of difficulty in this seminar is varying between the different topics. The audience is at least supposed to be familiar with basic probability. There are a few talks that require the lecture Stochastics II.
Bachelor and Master Students of any mathematical study course.
The "(B)" in the list of talks, means that this talk is supposed to be given by a Bachelor's Student.
Processes and fields with long-memory: Long-memory processes are known to play an important role in many scientific disciplines and applied fields such as geophysics, hydrology, economics, finance, telecommunications, network engineering, etc. In this course we investigate the connections between long-memory and other notions of interest, most importantly scaling and self-similarity. Self-similar processes such as fractional Brownian motion are stochastic processes that are invariant in distribution under suitable scaling of time and space. These processes can typically be used to model random phenomena with long-range dependence.The seminar starts with considering linear processes and self-similar processes. The next part is devoted to limit theorems in different frameworks. At the end we consider the generalization of long-range dependence to the case of higher dimensions.
(The picture shows the example of stochastic process with long range dependence)
